WlNDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 290,496, dated December 18,

Application tiled Juno 1S, 1883. (No model.)

To CLZ whom it may concern,.-

Be it known that I, Josinn lV. Tironrsor, of Milton, county of Norfolk, State of Massachusetts, have invented an improvement in a "Window-Screen, of which the following description, in connection with the accompanying drawings, is a specification, like let-ters on the drawings representing like parts.

My invention relates to a Window-screen of that class .in which a ilexibleiscreen is mounted on a roller after the manner of the usual window-shades, and is connected-with the sash and drawn out or unrollcd in proportion as the sash is raised or opened, to thus cover the space opened by the sash and prevent the ingross of ilies and mosquitoes or other insects.

In the accompanying drawings, Figure 1 is a front elevation, and Fip. 2 a vertical longi tudinal section, of a window provided with a screen embodying this invention.

The window-frame a contains the usual sliding sashes, b c, which may be balanced by Weights d in the usual manner. When the screen is to be used with the lower sash, it is mounted on a winding` roller., c, near the bottoni of the window-frame, tl said roller being operated by a spring to ep the screen f, which consists of any suital'fle ilexiblc 'fabric or webbing wound upon it :when not in use, and to hold it drawn tightly in place when in use. The said screen is lcd from the roller c over a guide-roller, 71., located close to the sill orlower portion of the window-frame, and is connected with a cross-piece, fi, adapted to slide in guides k at the sides of the windowframe, the said guides also holding the edges of the screen when the said cross-piece 'i is raised. The cross-piece z' is provided with T-shaped notches n1, to receive the i'lattened shanks of buttons n, which, when turned into verti cal position, will allow the said shanks to pass freely through the said notches, so that the sash may be raised without carrying` the screen with it when desired tohave a free opening through the window. When, however,the buttons are turned to the horizontal position, as shown, the shanks of the buttons engage the cross-piece i, fastening itto the lower railhof the sash and causing` it to move therewith, so that as the sash is raised or the windenr is opened the screen is drawn out to cover thc opening. The guideroller h never has but a single thickness of the screen over it, and consequently may be placed to keep the said screen close to the sill, so that no space is allorded for the entrance of insects, its effective part thus always having the same position with relation to the frame, whether a greater or less amount is unwound lfreni the window c; but when the screen is unwound directly from the roller c vWithout the guide-roller Il., as has usually been praeticcd in window-screens of similar character, a space will be left below the said roller by the unwinding` of the different layers of the screen material from it.

The roller c may, if desired, be inclosed by a guard, o, and a screen may, if desired, 1"* employed in a similar manner in connectie with the upper sash, as shown in dotted line: Fig. 2, it also having` a guide-roller to keep i' close to the window-frame.

The guide it is shown as a groove in the usual removable strip at the side ot' the window by which the sash is held in the frame, and the lower portion, p, of the said strip, containing the bearings for the rollers c and h, may, it desired, be made separate 4freni the remainder of the strip, as shown, so as to enable the entire screen to be removed, if desired, the said portions p being` normally held in place by suitable iastenings, shown as hooks o.

A screen of this construction oi' iine mate rial may be used in railway-cars to admit air and exclude the cinders, and it is obvious that the screen proper may be made of any kind of material suitable for the use to which it is to be put. The screen may, if desired, be raised or drawn out without raising the sash for the purpose of partly obstructing,` the view through the window. When the screen is use@ with the upper sash, the guide k may be madt in the parting-bead for the sashcs.
